Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 147,001,465, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 147,001,465 | |
| -1 | -147,001,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,001,465.
Example:
1 x 147,001,465 = 147,001,465
and
-1 x -147,001,465 = 147,001,465
Notice both answers equal 147,001,465
With that explanation out of the way, let's continue. Next, we take the number 147,001,465 and divide it by 2:
147,001,465 ÷ 2 = 73,500,732.5
If the quotient is a whole number, then 2 and 73,500,732.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 147,001,465 | |
| -1 | -147,001,465 |
Now, we try dividing 147,001,465 by 3:
147,001,465 ÷ 3 = 49,000,488.3333
If the quotient is a whole number, then 3 and 49,000,488.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 147,001,465 | |
| -1 | -147,001,465 |
Let's try dividing by 4:
147,001,465 ÷ 4 = 36,750,366.25
If the quotient is a whole number, then 4 and 36,750,366.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 147,001,465 | |
| -1 | 147,001,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 133,033 | 665,165 | 1,729,429 | 2,261,561 | 8,647,145 | 11,307,805 | 29,400,293 | 147,001,465 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -133,033 | -665,165 | -1,729,429 | -2,261,561 | -8,647,145 | -11,307,805 | -29,400,293 | -147,001,465 |
